What is Cursor AI Editor?

Cursor is an AI-powered code editor built on VS Code with Claude 4.5 Sonnet integration. It features Tab completion for 30-50% faster coding, Cmd+K for surgical edits, AI Chat (Cmd+L) for questions and debugging, and Composer for multi-file editing.

How do I use Tab completion in Cursor?

Tab completion in Cursor predicts 1-15 lines of code. Start typing a function name or code pattern, and press Tab to accept the AI suggestion. Use Cmd+→ to accept word-by-word, and Alt+[ or Alt+] to cycle through alternatives.

What is Cmd+K in Cursor?

Cmd+K (Ctrl+K on Windows/Linux) is Cursor's inline editing feature. Select code, press Cmd+K, describe your change in plain English (like 'add error handling' or 'convert to TypeScript'), and Cursor makes the edit instantly.

How do @ symbols work in Cursor?

@ symbols provide context to Cursor's AI: @Files references specific files, @Folders references directories, @Codebase searches your entire project, @Docs queries official documentation, and @Web searches the internet. They dramatically improve AI accuracy.

What are Cursor Rules?

Cursor Rules are custom instructions in a .cursorrules file that tell the AI how to generate code for your project. They enforce coding standards, preferred libraries, file organization, and team conventions automatically.
